Michael Crabtree has arrived

SAN FRANCISCO — This used to be Frank Gore’s offense. He’s still good — he rushed 22 times for 119 yards and a touchdown against the Green Bay Packers — but Saturday he wasn’t even the 49ers’ best running back. That was quarterback Colin Kaepernick, who rushed 16 times for 181 yards and two touchdowns.

Now, Gore is one of the many good complimentary players on the 49ers’ offense

And now, the main thrust of the 49ers’ offense is to get the ball to wide receiver Michael Crabtree.
